Circulation type RoHS Compliant Features Further Evolution of High-accuracy Temperature Control Achieve high energy-saving performance ■Our acclaimed ±0.1℃ oil temperature control has been extended to cover an even wider range. ■Achieve high energy-saving performance with the adoption of a Daikin original IPM motor and R410A refrigerant for high COP characteristics. ■The cooling capacity resolution in the low-load range has been improved through optimal control of the compressor and electronic expansion valve. ■The power consumption can be checked on Reduction of the operation panel....

Features Functions featured ■The ingress protection of the control box has been upgraded (equivalent to IP54). ■Refrigerant gas leakage detection alarm function An alarm signal is output when the refrigerant gas would be leaked (as cooling circuit failure). ■Oil temperature warning function A warning signal can be output when the oil temperature or air temperature strays outside arbitrarily setting range. ■Electronic components resistant to sulfidization have been adopted. Higher durability for long-distance transportation ■Auto tuning function This function substantially cuts the time...

Oil Cooling Unit horsepower(HP) Note) *1. The cooling capacity represents the value at the standard point(inlet oil temperature: 35°C, room temperature: 35°C, oil for use: ISO VG32). The tolerance of the product is approx .±5%. *2. Be sure to use a commercial power supply for the power source. The use of an inverter power supply may cause burn damage to the unit. The voltage fluctuation range should be within ±10%. If the voltage fluctuation range is more than ±10%, please consult us. *3. There are three types of different voltage specifications depending on the power source: —046, —047 and...
